The EL5123C, EL5223C, EL5323C, and EL5423C are low power,
high voltage rail-to-rail input/output buffers designed primarily for use
in reference voltage buffering applications for TFT_LCDs. They are
avai labl e i n quad (EL5123C), octal (EL5223C), 10-channel
(EL5323C), and 12-channel (EL5423C) topologies. All buffers feature
a -3dB bandwidth of 12MHz and operate from just 600µA per buffer.
This family also features fast slewing and settling times, as well as a
continuous output drive capability of 30mA (sink and source).
The quad channel EL5123C is available in the 10-pin MSOP package.
The 8-channel EL5223C is available in both the 20-pin TSSOP and
24-pin LPP packages, the 10-channel EL5323C in the 24-pin TSSOP
and 24-pin LPP packages, and the 12-channel EL5423C in the 28-pin
TSSOP and 32-pin LPP packages. All buffers are specified for opera-
tion over the full -40°C to +85°C temperature range.

Note:
All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication; however, this data sheet cannot be a “controlled document”. Current revisions, if any, to these
specifications are maintained at the factory and are available upon your request. We recommend checking the revision level before finalization of your design documentation.
Values beyond absolute maximum ratings can cause the device to be pre-
maturely damaged. Absolute maximum ratings are stress ratings only and
functional device operation is not implied.
